Definitions
- This invention relates to an artificial vertebral disk replacement and method.
- the spinal column is a biomechanical structure composed primarily of ligaments, muscles, vertebrae and intervertebral disks.
- the biomechanical functions of the spine include: (1) support of the body, which involves the transfer of the weight and the bending movements of the head, trunk and arms to the pelvis and legs, (2) complex physiological motion between these parts, and (3) protection of the spinal cord and nerve roots.
- U.S. Pat. No. 4,714,469 to Kenna discloses a spinal implant that fuses vertebrae to the implant.
- the implant has a rigid body that fits between the vertebra with a protuberance extending from a vertebral contacting surface and extends into the vertebral body.
- U.S. Pat. No. 5,258,031 to Salib et al. discloses another prosthetic disk with a ball that fits into a socket.
- U.S. Pat. Nos. 5,425,773 and 5,562,738 are related patents to Boyd et al. that disclose a disk arthroplasty device for replacement of the spinal disk. A ball-and-socket are provided to enable rotation.
- U.S. Pat. No. 5,534,029 to Shima discloses an articulated vertebral body spacer with a pair of upper and lower joint pieces inserted between the vertebra. An intermediate layer is provided to allow for movement between the upper joint piece and the lower joint piece.
- U.S. Pat. No. 5,782,832 to Larsen et al. discloses a two-piece ball-and-socket spinal implant with upper and lower plates for insertion within the intervertebral space.
- U.S. Pat. No. 6,156,067 to Bryan et al. discloses a prosthesis having two plates with a nucleus there between.
- An embodiment of the present invention is directed to providing an implant for alleviating discomfort associated with the spinal column.
- the implant is characterized by having a first plate and a second plate with a spacer therebetween. The spacer fits within cavities on each of the first and second plate.
- FIG. 1A is a side perspective view of an embodiment of the assembled implant of the invention.
- FIG. 1B is an alternative side perspective view of an embodiment of the assembled implant of the invention.
- FIG. 2A and FIG. 2B show perspective views of the facing surfaces of the first plate and the second plate of an embodiment of the implant of the invention.
- FIG. 2 c through FIG. 2F show cross-sectional views of the first plate and the second plate of an embodiment of the implant of the invention.
- FIG. 3A is a perspective view of the spacer of an embodiment of the implant of the invention.
- FIG. 3B and FIG. 3 c are cross-sections of the spacer of an embodiment of the implant of the invention taken at 90° angles respective to each other.
- FIG. 4A is a cross-section of an embodiment of the implant of the invention taken along a plane parallel to the sagittal plane.
- FIG. 4B is a cross-section of an embodiment of the implant of the invention corresponding to a plane parallel to the location of the coronal plane after the implant has been implanted.
- FIG. 1A shows an embodiment of the implant 100 of the invention.
- the implant 100 has a first part 110 that is configured to mate with a first vertebra and a second part 120 that is configured to mate with a second vertebra.
- the first part 110 is a first or upper plate and the second part 120 is a second or lower plate.
- a third part 130 sits between the first part 110 and the second part 120 .
- the third part 130 acts as a spacer between the first part 110 and the second part 120 and facilitates pivotal movement of the first plate 110 and second plate 120 , relative to each other.
- the upper plate 110 has a first surface 112 from which a keel 114 extends.
- the first surface 112 or upper surface, abuts the vertebral body when the implant 100 is implanted.
- the first keel 114 extends into the vertebral body to anchor the implant into position.
- the keel 114 includes teeth 115 that assist in keeping the keel in position once the implant 100 is positioned between vertebral bodies.
- the teeth 115 point anteriorly in order to prevent the implant 100 from moving in an anterior direction.
- the second surface 116 or lower surface, engages the third part 130 of the implant and faces the second plate 120 .
- the second surface 116 can form a planar surface that is parallel to the first surface 112 , or can form a planar surface that is unparallel to the first surface 112 in order, in one embodiment, to allow the first plate 110 and the second plate 120 to be able to pivot to a greater degree with respect to each other. It is to be understood that other factors such as the height of the spacer 130 can also be adjusted in order to increase the degree that the first plate 110 and the second plate 120 can pivot relative to each other.
- planar surfaces corresponding to the first surface 112 and the second surface 116 of the first plate 110 lie within, or substantially within, the axial plane of the body while the first keel 114 (which is at or near a 90° angle from the surfaces 112 , 116 ) is aligned within the sagittal plane of the body.
- the lower plate 120 has a first surface 122 from which a keel 124 extends.
- the first surface 122 or lower surface, abuts the vertebral body when the implant 100 is implanted.
- the second keel 124 extends into the vertebral body to anchor the implant into position.
- the keel 124 includes teeth 125 that assist in keeping the keel in position once the implant 100 is positioned between vertebral bodies.
- the teeth 125 point anteriorly in order to prevent the implant 100 from moving in an anterior direction.
- the second surface 126 or upper surface, engages the third part 130 of the implant and faces the first plate 110 .
- the second surface 126 can form a planar surface that is parallel to the first surface 122 , or can form a planar surface that is not parallel to the first surface in order, in one embodiment, to allow the first plate 110 and the second plate 120 to be able to pivot or rotate to a greater degree with respect to each other.
- the first surface 112 of the first plate 110 can form a planar surface that is parallel to a planar surface formed by the first surface 122 of the second plate 120 when the implant 100 is assembled and is in a neutral position (i.e., the position where the first plate 110 has not rotated relative to the second plate 120 ).
- the first surface 112 of the first plate 110 can form a planar surface that is not parallel to the planar surface of the first surface 122 of the second plate 120 when the implant 100 is assembled and in a neutral position in order to accommodate the geometry of adjacent end plates of adjacent vertebral bodies. Such non-parallel surface in certain situations could eliminate a need to modify the surface of the end plates in order to accommodate the implant 100 .
- planar surfaces corresponding to the first surface 122 and the second surface 126 of the second plate 120 lie within, or substantially within, the axial plane of the body while the second keel 124 (which is at or near a 90° angle from the surfaces 122 , 126 ) is aligned within the sagittal plane of the body.
- FIG. 1B shows an alternative perspective view of the implant 100 of the invention shown in FIG. 1A.
- the implant 100 has a first part 110 that is configured to mate with a first vertebra and a second part 120 that is configured to mate with a second vertebra.
- the third part 130 acts as a spacer to separate the first part 110 from the second part 120 and to allow the first plate 110 and the second plate 120 to pivot or rotate relative to each other.
- FIG. 2A shows a perspective view of the top plate 110 of the implant 100 of the invention.
- the first surface 112 of the top plate 110 is configured to contact the vertebral body when the implant 100 is implanted.
- the first surface 112 has a first keel 114 extending therefrom (shown in FIGS. 1A and 1B).
- the second surface 116 of the top plate 110 has a cavity 210 or socket formed thereon.
- the cavity is a convex cylindrical surface. An example of the relative dimensions of the cavity 210 , are discussed with respect to FIG. 2 c and FIG. 2D below.
- the cavity 210 includes the shallow convex surface 211 with ends 213 and 215 that are, in this particular embodiment, substantially perpendicular to the surface 116 .
- ends 213 and 215 essentially form perpendicular ends of a cylindrical void of cavity 210 defined by the convex surface 211 and the ends 213 and 215 .
- the cavity 210 allows the spacer 130 to pivot or rotate about a first axis 217 that is about perpendicular to the ends 213 and 215 or in other words about an axis for the cylindrical void defined by cavity 210 .
- the ends 213 and 215 block motion of the spacer 130 about a second axis 219 that is perpendicular to the first axis 217 .
- the second axis 219 is parallel to the keels 114 and 124 .
- the cavity 210 in this preferred embodiment includes side walls or ends 213 and 215 that have crests 233 and 235 respectively that project into the cavity 210 .
- the convex surface 211 has edges 234 and 236 with crests 237 and 239 .
- the crests 233 , 235 , 237 , and 239 allow a loose fit between the spacer 130 and the cavity 210 . This loose fit in turn allows the implant to twist in a direction that is perpendicular to the flat plain of the first plate 110 about an axis that is about parallel to the axis of the spine.
- the implant 100 allows the spine to have movment in three orthogonal degrees of freedom, namely (1) forward and backward bending movement, (2) lateral side-to-side bending, and (3) twisting movement.
- the cavity 240 in the lower plate 120 can also have the same design as the cavity 210 in the upper plate 110 with an increase in the amount of twisting movement afforded by the implant 110 .
- loose fit generally between one or both of the cavities 210 and 240 and the spacer 130 can allow for twisting motion.
- the spacer 130 can also be made with crests on the curved surfaces and on the ends in order to afford similar twisting motion.
- FIG. 2B shows a perspective view of the bottom plate 120 of the implant 100 of the invention.
- the first surface 122 of the bottom plate 120 is configured to contact the vertebral body when the implant 100 is implanted.
- the first surface 122 has a second keel 124 extending therefrom.
- the second surface 126 of the top plate 120 has a cavity 240 or socket formed thereon.
- the cavity 240 is a convex cylindrical surface. An example of the relative dimensions of the cavity 240 are discussed in more detail with respect to FIG. 2E and FIG. 2F below.
- the cavity 240 includes the shallow convex surface 241 with ends 243 and 245 that are in this particular embodiment substantially perpendicular to the surface 126 .
- ends 243 and 245 essentially form perpendicular ends of a cylindrical void of cavity 241 defined by the convex surface 241 and the ends 243 and 245 .
- the cavity 240 allows the spacer 130 to pivot or rotate about a first axis 247 that is about perpendicular to the ends 243 and 245 or, in other words, about an axis for the cylindrical void defined by cavity 240 .
- the ends 243 and 245 block motion of the spacer 130 about a second axis 249 that is perpendicular to the first axis 247 .
- the first axis 247 is parallel to the keels 114 and 124 .
- first axis 247 for second plate 120 about which the spacer 130 can pivot or rotate is perpendicular to the first axis 217 of the first plate 110 about which the spacer 130 can pivot or rotate.
- the cavity of the first or upper plate 110 blocks movement of the spacer in a direction that is perpendicular to the keels 114 and 124 while allowing the first plate 110 to pivot or rotate about the first axis 217 , an axis that is perpendicular to the keels 114 and 124 .
- the spacer 130 is not required to move in order to emulate the degrees of freedom associated with the back as the ends of the cavities 210 and 240 block movement of the spacer 130 .
- the fit of the spacer in the cavities 210 and 240 can be loose allowing the spacer to allow the first plate 210 to be able to twist somewhat relative to the second plate 240 .
- This twisting action would generally be about an axis that is perpendicular to the facing surfaces 116 and 126 of the first and second plates 110 and 120 , respectively.
- the fit can be tighter in order to restrict such twisting action.
- FIG. 2 c and FIG. 2D a cross-section of the top plate 110 of the implant 100 of the invention is shown.
- FIG. 2 c is a cross-section taken along a plane that would correspond to a plane that is parallel to the median sagittal plane of the body after the implant was implanted.

- This invention relates to an artificial vertebral disk replacement and method.
- The spinal column is a biomechanical structure composed primarily of ligaments, muscles, vertebrae and intervertebral disks. The biomechanical functions of the spine include: (1) support of the body, which involves the transfer of the weight and the bending movements of the head, trunk and arms to the pelvis and legs, (2) complex physiological motion between these parts, and (3) protection of the spinal cord and nerve roots.
- As the present society ages, it is anticipated that there will be an increase in adverse spinal conditions which are characteristic of older people. Pain associated with such conditions can be relieved by medication and/or surgery. Of course, it is desirable to eliminate the need for major surgery for all individuals, and, in particular, for the elderly.
- More particularly, over the years, a variety of intervertebral implants have been developed in an effort to relieve the pain associated with degenerative and dysfunctional disk conditions. For example, U.S. Pat. No. 4,349,921 to Kuntz discloses an intervertebral disk prosthesis.
- U.S. Pat. No. 4,714,469 to Kenna discloses a spinal implant that fuses vertebrae to the implant. The implant has a rigid body that fits between the vertebra with a protuberance extending from a vertebral contacting surface and extends into the vertebral body.
- U.S. Pat. No. 5,258,031 to Salib et al. discloses another prosthetic disk with a ball that fits into a socket.
- U.S. Pat. Nos. 5,425,773 and 5,562,738 are related patents to Boyd et al. that disclose a disk arthroplasty device for replacement of the spinal disk. A ball-and-socket are provided to enable rotation.
- U.S. Pat. No. 5,534,029 to Shima discloses an articulated vertebral body spacer with a pair of upper and lower joint pieces inserted between the vertebra. An intermediate layer is provided to allow for movement between the upper joint piece and the lower joint piece.
- U.S. Pat. No. 5,782,832 to Larsen et al. discloses a two-piece ball-and-socket spinal implant with upper and lower plates for insertion within the intervertebral space.
- U.S. Pat. No. 6,156,067 to Bryan et al. discloses a prosthesis having two plates with a nucleus there between.
- None of these solutions provide an implant that restores a wide range of natural movement.
- Accordingly, there needs to be developed implants for alleviating such conditions, and for restoring natural movement.
- An embodiment of the present invention is directed to providing an implant for alleviating discomfort associated with the spinal column. The implant is characterized by having a first plate and a second plate with a spacer therebetween. The spacer fits within cavities on each of the first and second plate.

- The following description is presented to enable any person skilled in the art to make and use the invention. Various modifications to the embodiments described will be readily apparent to those skilled in the art, and the principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of the present invention as defined by the appended claims. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein. To the extent necessary to achieve a complete understanding of the invention disclosed, the specification and drawings of all patents and patent applications cited in this application are incorporated herein by reference
- FIG. 1A shows an embodiment of the
implant 100 of the invention. Theimplant 100 has afirst part 110 that is configured to mate with a first vertebra and asecond part 120 that is configured to mate with a second vertebra. Thefirst part 110 is a first or upper plate and thesecond part 120 is a second or lower plate. Athird part 130 sits between thefirst part 110 and thesecond part 120. Thethird part 130 acts as a spacer between thefirst part 110 and thesecond part 120 and facilitates pivotal movement of thefirst plate 110 andsecond plate 120, relative to each other. - The
upper plate 110 has afirst surface 112 from which akeel 114 extends. Thefirst surface 112, or upper surface, abuts the vertebral body when theimplant 100 is implanted. Thefirst keel 114 extends into the vertebral body to anchor the implant into position. Thekeel 114 includesteeth 115 that assist in keeping the keel in position once theimplant 100 is positioned between vertebral bodies. Generally, in a preferred embodiment that is to be implanted by an anterior approach, theteeth 115 point anteriorly in order to prevent theimplant 100 from moving in an anterior direction. Thesecond surface 116, or lower surface, engages thethird part 130 of the implant and faces thesecond plate 120. Thesecond surface 116 can form a planar surface that is parallel to thefirst surface 112, or can form a planar surface that is unparallel to thefirst surface 112 in order, in one embodiment, to allow thefirst plate 110 and thesecond plate 120 to be able to pivot to a greater degree with respect to each other. It is to be understood that other factors such as the height of thespacer 130 can also be adjusted in order to increase the degree that thefirst plate 110 and thesecond plate 120 can pivot relative to each other. - When the implant is implanted between vertebral bodies the planar surfaces corresponding to the
first surface 112 and thesecond surface 116 of thefirst plate 110 lie within, or substantially within, the axial plane of the body while the first keel 114 (which is at or near a 90° angle from thesurfaces 112, 116) is aligned within the sagittal plane of the body. - The
lower plate 120 has afirst surface 122 from which akeel 124 extends. Thefirst surface 122, or lower surface, abuts the vertebral body when theimplant 100 is implanted. Thesecond keel 124 extends into the vertebral body to anchor the implant into position. Thekeel 124 includesteeth 125 that assist in keeping the keel in position once theimplant 100 is positioned between vertebral bodies. Generally, in a preferred embodiment that is to be implanted by an anterior approach, theteeth 125 point anteriorly in order to prevent theimplant 100 from moving in an anterior direction. Thesecond surface 126, or upper surface, engages thethird part 130 of the implant and faces thefirst plate 110. Thesecond surface 126 can form a planar surface that is parallel to thefirst surface 122, or can form a planar surface that is not parallel to the first surface in order, in one embodiment, to allow thefirst plate 110 and thesecond plate 120 to be able to pivot or rotate to a greater degree with respect to each other. Thefirst surface 112 of thefirst plate 110 can form a planar surface that is parallel to a planar surface formed by thefirst surface 122 of thesecond plate 120 when theimplant 100 is assembled and is in a neutral position (i.e., the position where thefirst plate 110 has not rotated relative to the second plate 120). Alternatively, thefirst surface 112 of thefirst plate 110 can form a planar surface that is not parallel to the planar surface of thefirst surface 122 of thesecond plate 120 when theimplant 100 is assembled and in a neutral position in order to accommodate the geometry of adjacent end plates of adjacent vertebral bodies. Such non-parallel surface in certain situations could eliminate a need to modify the surface of the end plates in order to accommodate theimplant 100. - As with the first plate, when the implant is implanted between vertebral bodies the planar surfaces corresponding to the
first surface 122 and thesecond surface 126 of thesecond plate 120 lie within, or substantially within, the axial plane of the body while the second keel 124 (which is at or near a 90° angle from thesurfaces 122, 126) is aligned within the sagittal plane of the body. - FIG. 1B shows an alternative perspective view of the
implant 100 of the invention shown in FIG. 1A. Again, theimplant 100 has afirst part 110 that is configured to mate with a first vertebra and asecond part 120 that is configured to mate with a second vertebra. Thethird part 130 acts as a spacer to separate thefirst part 110 from thesecond part 120 and to allow thefirst plate 110 and thesecond plate 120 to pivot or rotate relative to each other. - FIG. 2A shows a perspective view of the
top plate 110 of theimplant 100 of the invention. Thefirst surface 112 of thetop plate 110 is configured to contact the vertebral body when theimplant 100 is implanted. Thefirst surface 112 has afirst keel 114 extending therefrom (shown in FIGS. 1A and 1B). Thesecond surface 116 of thetop plate 110 has acavity 210 or socket formed thereon. The cavity is a convex cylindrical surface. An example of the relative dimensions of thecavity 210, are discussed with respect to FIG. 2c and FIG. 2D below. Thecavity 210 includes the shallowconvex surface 211 withends surface 116. These ends 213 and 215 essentially form perpendicular ends of a cylindrical void ofcavity 210 defined by theconvex surface 211 and theends spacer 130, thecavity 210 allows thespacer 130 to pivot or rotate about afirst axis 217 that is about perpendicular to theends cavity 210. The ends 213 and 215 block motion of thespacer 130 about asecond axis 219 that is perpendicular to thefirst axis 217. In this embodiment, it is noted that thesecond axis 219 is parallel to thekeels cavity 210 in this preferred embodiment includes side walls or ends 213 and 215 that havecrests 233 and 235 respectively that project into thecavity 210. Additionally, theconvex surface 211 hasedges crests crests spacer 130 and thecavity 210. This loose fit in turn allows the implant to twist in a direction that is perpendicular to the flat plain of thefirst plate 110 about an axis that is about parallel to the axis of the spine. Thus, theimplant 100 allows the spine to have movment in three orthogonal degrees of freedom, namely (1) forward and backward bending movement, (2) lateral side-to-side bending, and (3) twisting movement. It is to be understood that thecavity 240 in thelower plate 120 can also have the same design as thecavity 210 in theupper plate 110 with an increase in the amount of twisting movement afforded by theimplant 110. As is noted elsewhere herein, loose fit generally between one or both of thecavities spacer 130 can allow for twisting motion. Further thespacer 130 can also be made with crests on the curved surfaces and on the ends in order to afford similar twisting motion. - FIG. 2B shows a perspective view of the
bottom plate 120 of theimplant 100 of the invention. Thefirst surface 122 of thebottom plate 120 is configured to contact the vertebral body when theimplant 100 is implanted. As indicated above, thefirst surface 122 has asecond keel 124 extending therefrom. Thesecond surface 126 of thetop plate 120 has acavity 240 or socket formed thereon. Thecavity 240 is a convex cylindrical surface. An example of the relative dimensions of thecavity 240 are discussed in more detail with respect to FIG. 2E and FIG. 2F below. Thecavity 240 includes the shallowconvex surface 241 withends surface 126. These ends 243 and 245 essentially form perpendicular ends of a cylindrical void ofcavity 241 defined by theconvex surface 241 and theends spacer 130, thecavity 240 allows thespacer 130 to pivot or rotate about afirst axis 247 that is about perpendicular to theends cavity 240. The ends 243 and 245 block motion of thespacer 130 about asecond axis 249 that is perpendicular to thefirst axis 247. In this embodiment, it is noted that thefirst axis 247 is parallel to thekeels first axis 247 forsecond plate 120 about which thespacer 130 can pivot or rotate is perpendicular to thefirst axis 217 of thefirst plate 110 about which thespacer 130 can pivot or rotate. Thus, as will also be described below, the cavity of the first orupper plate 110 blocks movement of the spacer in a direction that is perpendicular to thekeels first plate 110 to pivot or rotate about thefirst axis 217, an axis that is perpendicular to thekeels spacer 130 is not required to move in order to emulate the degrees of freedom associated with the back as the ends of thecavities spacer 130. However, it is to be understood that in a preferred embodiment, the fit of the spacer in thecavities first plate 210 to be able to twist somewhat relative to thesecond plate 240. This twisting action would generally be about an axis that is perpendicular to the facingsurfaces second plates - Turning now to FIG. 2c and FIG. 2D, a cross-section of the
top plate 110 of theimplant 100 of the invention is shown. FIG. 2c is a cross-section taken along a plane that would correspond to a plane that is parallel to the median sagittal plane of the body after the implant was implanted. Thefirst surface 112 of the plate is configured to contact the vertebral body when theimplant 100 is implanted. Thefirst surface 112 has afirst keel 114 extending therefrom that extends into the vertebral body when implanted. Thesecond surface 116 of theupper plate 110 has acavity 210 formed thereon. In this figure, thecavity 210 has afirst dimension 212. In thefirst dimension 212, thecavity 210 is concave such that it is curved like the inner surface of a cylinder. - FIG. 2D is a cross-section taken along a plane that would correspond to a plane that is parallel to the frontal (coronal) plane of the body after the implant was implanted. FIG. 2D also illustrates the
first surface 112 of the plate with thefirst keel 114. Thesecond surface 116 of theupper plate 110 has acavity 210 formed thereon. Thecavity 210 has asecond dimension 214. Thesecond dimension 214 is in the form of a trough or “flattened-U” with a previously indicated concavebottom surface 211 and two ends orsidewalls sidewalls bottom surface 211. However, as will be appreciated by those of skill in the art, the ends orsidewalls - FIG. 2c and FIG. 2D are oriented to illustrate that the
first dimension 212 shown in FIG. 2c and thesecond dimension 214 shown in FIG. 2D are perpendicular to each other. - Turning now to FIG. 2E and FIG. 2F, a cross-section of the
lower plate 120 of an embodiment of theimplant 100 of the invention is shown. FIG. 2E is a cross-section taken along a plane that would correspond to a plane that is parallel to the median sagittal plane of the body after the implant was implanted. FIG. 2E also illustrates thefirst surface 122 of thebottom plate 122 with thesecond keel 124. Thecavity 240 has afirst dimension 242. Thefirst dimension 242 is in the form of a trough or “flattened-U” with a bottomconcave surface 241 and two ends orsidewalls sidewalls bottom surface 241. However, as will be appreciated by those of skill in the art, the ends orsidewalls - FIG. 2F is a cross-section taken along a plane that would correspond to a plane that is parallel to the frontal (coronal) plane of the body after the implant was implanted. The
first surface 122 of the plate is configured to contact the vertebral body when theimplant 100 is implanted. Thefirst surface 122 has afirst keel 124 extending therefrom. Thesecond surface 126 of thebottom plate 120 has acavity 240 formed thereon. In this figure, thecavity 240 has asecond dimension 244. In thesecond dimension 244, thecavity 240 is concave such that it is curved like the inner surface of a cylinder. - FIG. 2c and FIG. 2D are oriented to illustrate that the
first dimension 212 shown in FIG. 2c and thesecond dimension 214 shown in FIG. 2D are perpendicular to each other, while FIG. 2E and FIG. 2F illustrate that thefirst dimension 242 is perpendicular tosecond dimension 244. Further, the curvedfirst dimension 212 of FIG. 2c is oriented perpendicularly to the curvedsecond dimension 244 of FIG. 2F, while thetrough dimension 214 of FIG. 2D is oriented perpendicularly to thetrough dimension 242 of FIG. 2E. It is noted that in FIGS. 2c through 2F that the facingsurfaces second cavities - In FIG. 3A, the
spacer 130 is depicted in perspective view. Thespacer 130 is dimensioned so that it has a curved or convexupper surface 310 and a curved or convexlower surface 320, respectively, corresponding with the opposing concave surfaces in theupper plate 110 and thelower plate 120. - As shown in FIG. 3A, the curved
upper surface 310 is bordered along its curved edge by a pair offirst sides second sides first sides first sides second sides upper edges first sides flat edges second sides lower edges 326, 328 extend to meet the ends of theflat edges first sides - FIG. 3B and FIG. 3c show cross-sections of the
spacer 130, shown in FIG. 3A. The cross-section of FIG. 3B is taken at a 90° angle from the cross-section shown in FIG. 3c. FIG. 3B is taken through a plane parallel to theends spacer 130 has a concaveupper surface 310 and a concavelower surface 320 and pairs ofparallel sides - FIG. 4A shows a cross-section of the
implant 100 in its assembled condition taken along a plane that would correspond to a plane that is parallel to the median sagittal plane of the body after the implant was implanted. Theimplant 100 has a firstupper plate 110 that is configured to mate with a first vertebra and a secondlower plate 120 that is configured to mate with a second vertebra. Thespacer 130 sits between thefirst plate 110 and thesecond plate 120. - FIG. 4B shows a cross-section of the
implant 100 in its assembled condition taken at 90° from the cross-section shown in FIG. 4A. Thus, the view of FIG. 4B is taken along a plane that would correspond to a plane that is parallel to the frontal (coronal) plane of the body after the implant was implanted. - It is to be understood that the embodiments of the invention can be made of titanium or medical guide stainless steel or other material that is approved for implantation in a patient and has appropriate characteristics. Alternatively, the
spacer 130 can be made out of a polymer, and more specifically, the polymer is a thermoplastic with the other components made of the materials specified above. Still more specifically, the polymer is a polyketone known as polyetheretherketone (PEEK). Still more specifically, the material is PEEK 450G, which is an unfilled PEEK approved for medical implantation available from Victrex of Lancashire, Great Britain. (Victrex is located at www.matweb.com or see Boedeker www.boedeker.com). Other sources of this material include Gharda located in Panoli, India (www.ghardapolvmers.com). Thespacer 130 can be formed by extrusion, injection, compression molding and/or machining techniques. This material has appropriate physical and mechanical properties and is suitable for carrying and spreading the physical load between the spinous process. Further in this embodiment, the PEEK has the following additional approximate properties:PROPERTY VALUE Density 1.3 g/cc Rockwell M 99 Rockwell R 126 Tensile Strength 97 MPa Modulus of Elasticity 3.5 GPa Flexural Modulus 4.1 GPa - It should be noted that the material selected may also be filled. For example, other grades of PEEK are also available and contemplated, such as 30% glass-filled or 30% carbon-filled, provided such materials are cleared for use in implantable devices by the FDA, or other regulatory body. Glass-filled PEEK reduces the expansion rate and increases the flexural modulus of PEEK relative to that which is unfilled. The resulting product is known to be ideal for improved strength, stiffness, or stability. Carbon-filled PEEK is known to enhance the compressive strength and stiffness of PEEK and lower its expansion rate. Carbon-filled PEEK offers wear resistance and load carrying capability.
- The spacer can also be comprised of polyetherketoneketone (PEKK). Other material that can be used include polyetherketone (PEK), polyetherketoneetherketoneketone (PEKEKK), and polyetheretherketoneketone (PEEKK), and, generally, a polyaryletheretherketone. Further, other polyketones can be used as well as other thermoplastics.
- Reference to appropriate polymers that can be used in the spacer can be made to the following documents, all of which are incorporated herein by reference. These documents include: PCT Publication WO 02/02158 A1, dated Jan. 10, 2002, entitled “Bio-Compatible Polymeric Materials;” PCT Publication WO 02/00275 A1, dated Jan. 3, 2002, entitled “Bio-Compatible Polymeric Materials;” and, PCT Publication WO 02/00270 A1, dated Jan. 3, 2002, entitled “Bio-Compatible Polymeric Materials.”
- In operation, the
implant 100 enables a forward bending movement and a rearward bending movement by sliding theupper plate 110 forward and backward over thespacer 130 relative to thelower plate 120. This movement is shown as rotation about theaxis 217 in FIG. 4A. - The
implant 100 enables a right lateral bending movement and a left lateral bending movement by sliding thelower plate 120 side-to-side over thespacer 130 relative toupper plate 110. This movement is shown as rotation about theaxis 219 in FIG. 4B. Additionally, with a loose fit between the first plate, the second plate and the spacer, rotational or twisting motion along an axis that is along the spine and perpendicular to the first and second plates is accomplished. - To implant the
implant 100 of this invention, the spine is exposed and then the intervertebral disk is removed. The implant is then inserted between two vertebrae and the wound is closed. This procedure can be followed for either an anterior approach or posterior approach. For an anterior approach, which due to the anatomy of the body may be preferred, the teeth would be pointed toward the anterior in order to aid in retaining the implant in place. For a posterior approach, the teeth would point posteriorly. - Additional steps, such as cutting channels into the vertebral bodies to accept the keels of the plates and assembling the implant by inserting the spacer between the upper and lower plate prior to installation can also be performed without departing from the scope of the invention.
- It is to be appreciated that although the first and second plates are depicted as having concave cavities and the spacer is depicted as having two convex surfaces that are oriented about perpendicular to each other, that other embodiments of the invention can have other configurations. For example, the first and second plates can have convex protrusions, such as, for example, cylindrical protrusions that are shaped to mate with concave surfaces of a spacer, with the concave surfaces of the spacer oriented about perpendicular to each other. In this embodiment, the convex protrusions of the first and the second plates could preferably each have a pair of parallel side walls that would act as the side walls in the depicted embodiments in order to block motion of the spacer. Also, it is to be appreciated that in still another embodiment, the spacer can have upper and lower truncated convex spherical surfaces with two pairs of side walls, instead of cylindrical surfaces with side walls, and be in the scope and spirit of the invention. In this embodiment, each of the first and second plates would have truncated concave spherical surfaces with a pair of side walls. In still a further embodiment, each of the first and second plates could have spherical protrusions with a pair of side walls and the spacer could have first and second spherical concave surfaces with two pairs of side walls joining the first and second spherical concave surfaces. Still alternatively, the first plate can have a concave surface and blocking side walls and the mating portion of the spacer can be convex with the second plate having a convex protrusion with the mating portion of the spacer, or being concave, with blocking side walls.
- The foregoing description of embodiments of the present invention has been provided for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations will be apparent to the practitioner skilled in the art.
